Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33227 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.activemq:activemq-all (Maven): affected all versions; fixed in 5.19.3\n- org.apache.activemq:activemq-all (Maven): affected all versions; fixed in 5.19.3\n- org.apache.activemq:activemq-all (Maven): affected from 6.0.0; fixed in 6.2.2\n- org.apache.activemq:activemq-all (Maven): affected from 6.0.0; fixed in 6.2.2\n- activemq (Bitnami): affected all versions; fixed in 5.19.3, 6.2.2\n- org.apache.activemq:activemq-broker (Maven): affected all versions; fixed in 5.19.3\n- org.apache.activemq:activemq-broker (Maven): affected all versions; fixed in 5.19.3\n- org.apache.activemq:activemq-broker (Maven): affected from 6.0.0; fixed in 6.2.2\n- org.apache.activemq:activemq-broker (Maven): affected from 6.0.0; fixed in 6.2.2\n- org.apache.activemq:activemq-client (Maven): affected all versions; fixed in 5.19.3\n- org.apache.activemq:activemq-client (Maven): affected all versions; fixed in 5.19.3\n- org.apache.activemq:activemq-client (Maven): affected from 6.0.0; fixed in 6.2.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-33227/ (Markdown: https://insights.sbomify.com/CVE-2026-33227/index.md)","id":"CVE-2026-33227","markdown":"https://insights.sbomify.com/CVE-2026-33227/index.md","name":"CVE-2026-33227","record":{"aliases":["BIT-activemq-2026-33227","DEBIAN-CVE-2026-33227","GHSA-h2h4-5m64-m273","MINI-9xg2-hrr3-5rq4","MINI-qg4w-8j9r-2m57","MINI-qxx3-8vj9-gq6v","MINI-v6f5-3v3r-ffpp","MINI-w7v5-gjjc-3q3m","MINI-wpf2-w3g2-6h98","ROOT-APP-MAVEN-CVE-2026-33227","UBUNTU-CVE-2026-33227"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache ActiveMQ","requires_auth":"low_privilege","summary":"Authenticated users can traverse the classpath via crafted keys in STOMP or Web console, potentially enabling resource loading attacks.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"activemq","vendor":"apache"},{"product":"activemq_broker","vendor":"apache"},{"product":"activemq_web","vendor":"apache"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Improper validation and restriction of a classpath path name vulnerability in \n\n Apache ActiveMQ Client, Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ Web, Apache ActiveMQ.\n\nIn two instances (when creating a Stomp consumer and also browsing messages in the Web console) an authenticated user provided \"key\" value could be constructed to traverse the classpath due to path concatenation.
